Carrier mufflers??

[Bruce Parker (RIP)]

I received two Walker 17864's today. We passed a broken down courier truck on the way home from work and I told my wife wouldn't it be ironic if it was delivering the mufflers. Turns out it was.

Comparing them to the originals, the body is exactly the right length and diameter. The inlets and outlets are the right size and leave lots of room to attach the correct pipes to. The only difference is that the top and bottom pipes are 180 degrees apart whereas the originals have one about 30 degrees rotated (or 'out of timing' as Rob says). I'll see how much play there is (ie if I can distribute the difference between the top and bottom) or if a new custom pipe needs to be made. For sure one side has to be right. My pipes are original WW2 and solid as a rock...I want to reuse them if I can.

One question: the Walkers have an arrow that points A in one direction and B in the other and are not marked 'inlet' and 'outlet'. Is there a convention that says whether A or B is the inlet/outlet?

Cut open and repair the internal baffles in your originals ... in the form of a question . . .?

In the form of an answer, I did that 6 years ago and ran with it. I now find myself where I am. Rot does set in.

And after a point the externals get punky too.

These mufflers are a multi-fit type and in the catalogue, depending on the application it would specify A or B for the inlet. In other words it doesn’t matter, the muffler is non- directional. Whichever way it fits best, put it on.

Thanks, and that makes sense. Looking inside it appears to be identical baffle tubes going the length of the muffler. I doubt there's more to it than that.

Note the info on "reversible". Then again, I am not sure if I directed the ones I have used (I have done 3 different carriers in the past few years using these mufflers). All are nice and quiet. I did drill a drain hole in the low spot of the mufflers as well as the pipes to allow water condensation to escape.

Right, I'd put one side on A up and the other B up and the damn carrier would pull to the left...
